Battery Charger - User Manual

4-1. GENERAL

Once the Charger is in position and all connections have been made per the Outline and Interconnect drawing, you are ready to proceed to the startup and test stages.

4-2. POWER VERIFICATION

At your power panel, switch on the AC power feeding the Charger. With a voltmeter, check the voltage level present at the AC input terminals and verify that they are the same as shown on the Outline and Interconnect drawing. If the levels are different shut down the power and contact Dependable Power Systems. NOTE: Rotation is not critical as this unit is self correcting.

Connect batteries to unit and close the external battery breaker if available. With a voltmeter, check the voltage and polarity at the battery input terminals and verify that they are the same as shown on the Outline and Interconnect Drawing. If the polarity is wrong, reverse the input battery cabling and recheck with a voltmeter. If the voltage levels are different, shut down the power and contact Dependable Power Systems. NOTE: The positive battery must connect to input terminal #22 and the negative connects to #21.

4-3. STARTUP

Close the AC INPUT breaker and the DC OUTPUT breaker, the unit will start, with the voltage and current walking up. The front panel meters should be functioning. Check the charger voltage and current. If the batteries are new or have set for a long time the charger may go into current limit. The output voltage will then be lower then the set point until the batteries demand for current is lower then the current limit level. If the output voltage is excessively lower then normal check batteries for bad or reversed cell(s) or an external short.

4-4. POWER FAILURE, RECTIFIER/CHARGER FAILURE SIMULATION

If either the AC input power is lost or the rectifier/charger fails, the rectifier/charger output will be lost and the external loads will operate off of the batteries. To simulate either of these failures, simply open the AC input circuit breaker (CB1). Notice the "AC ON" LED will not be illuminate. In the event of an actual power failure, this is exactly what you would see. In the unlikely event the system does not perform as specified, open the input and output breakers and contact the Dependable Power Systems service department.
